Engineering siderophore production in Pseudomonas to improve asbestos weathering

Microbial Biotechnology, 2022
Summary Iron plays a key role in microbial metabolism and bacteria have developed multiple siderophore‐driven mechanisms due to its poor bioavailability for organisms in the environment.

Pyoverdin is essential for virulence of Pseudomonas aeruginosa [PDF]

Infection and Immunity, 1996
The role of pyoverdin, the main siderophore in iron-gathering capacity produced by Pseudomonas aeruginosa, in bacterial growth in vivo is controversial, although iron is important for virulence. To determine the ability of pyoverdin to compete for iron with the human iron-binding protein transferrin, wild-type P. aeruginosa ATCC 15692 (PAO1 strain) and

Biogenesis of the Pyoverdin Chromophore

Zeitschrift für Naturforschung C, 1997
Abstract After growing Pseudomonas aeruginosa in the presence of 2 ,4-[4-15N]-diaminobutyric acid (Dab) its incorporation into the quinoline chromophore of the pyoverdin produced by this bacterium could be shown by mass and NMR-spectroscopic techniques.

Illuminating Siderophore Transporter Functionality with Thiopeptide Antibiotics

mBio, 2023
The Gram-negative opportunistic pathogen Pseudomonas aeruginosa is a leading cause of infections and mortality in immunocompromised patients. This organism can overcome iron deprivation during infection via the synthesis of two iron-chelating ...

Copper selects for siderophore-mediated virulence in Pseudomonas aeruginosa

BMC Microbiology, 2022
Background Iron is essential for almost all bacterial pathogens and consequently it is actively withheld by their hosts. However, the production of extracellular siderophores enables iron sequestration by pathogens, increasing their virulence.

Two new siderophores produced by Pseudomonas sp. NCIMB 10586: The anti-oomycete non-ribosomal peptide synthetase-dependent mupirochelin and the NRPS-independent triabactin

Frontiers in Microbiology, 2023
IntroductionGlobisporangium ultimum is an oomycetal pathogen causing damping-off on over 300 different plant hosts. Currently, as for many phytopathogens, its control relies in the use of chemicals with negative impact on health and ecosystems. Therefore,

Diastereomeric Pyoverdin-Chromium(III) Complexes

Zeitschrift für Naturforschung C, 2002
Coordination isomeric diastereomeric Cr3+ complexes of the pyoverdin of Pseudomonas aeruginosa ATCC 15692 could be separated by chromatography and characterized by spectroscopic methods.

Pyoverdine production

, 2018
Pyoverdine production of isolates sampled from cystic fibrosis patients. For each sample is given: the Patient ID, the clone type, the absolute pyoverdine production as RFU/OD, the sample location, the length of infection of the clone type and overall in

Positron Emission Tomography Imaging of Bacterial Infections With an Enterobactin Analog to Monitor Treatment Efficacy With a Catechol Antibiotic

Angewandte Chemie, Volume 138, Issue 17, 20 April 2026.
Synopsis. The [68Ga]GaIII‐TREN‐CAM radiochelate selectively accumulates in Gram‐negative sites of infection and noninvasively monitors treatment response a siderophore antibiotic. ABSTRACT Positron emission tomography (PET) is an emerging tool under clinical investigation for the detection of bacterial infections.

A compensatory RNase E variation increases Iron Piracy and Virulence in multidrug-resistant Pseudomonas aeruginosa during Macrophage infection.

PLoS Pathogens, 2023
During chronic cystic fibrosis (CF) infections, evolved Pseudomonas aeruginosa antibiotic resistance is linked to increased pulmonary exacerbations, decreased lung function, and hospitalizations.
